About this 3D model

It's for two pieces, added strength and width. Just mirrored and doubled up on the already nice model from jcaywood! You might want to take a 3mm drill bit to the inside of the holes real quick, as I didn't edit those and they were a little tight fitting. If I alter it I will put it back up with the bigger holes. This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/2tXCNjDEpgd
